yl Group-Containing Diamine Compound
[0291]2,2-Bis(3-amino-4-hydroxyphenyl)hexafluoropropane (also referred to as “BAHF”, hereinafter) (18.3 g (0.05 mole)) was dissolved in acetone (100 mL) and propylene oxide (17.4 g (0.3 mole)), and the resultant solution was cooled to −15° C. A solution prepared by dissolving 3-nitrobenzoyl chloride (20.4 g (0.11 mole)) in acetone (100 mL) was added dropwise to the cooled solution. After the dropwise addition, the solution was reacted at −15° C. for 4 hours and then the solution was allowed to warm to room temperature. A precipitated white solid material was collected by filtration and then dried under a reduced pressure at 50° C.
[0292]The solid material (30 g) was placed in a 300-mL stainless autoclave and then dispersed in methyl cellosolve (250 mL), and 5% palladium-carbon (2 g) was added to the solution. Hydrogen was introduced into the solution using a balloon to carry out a reduction reaction at room temperature. After about 2 hours, the rea...

-Soluble Resin (A-1)
[0294]Under a dried nitrogen stream, BAHF (29.30 g (0.08 mole)), 1,3-bis(3-aminopropyl)tetramethyldisiloxane (1.24 g (0.005 mole, SiDA)) and 3-aminophenol (3-APh, manufactured by Tokyo Chemical Industry Co., Ltd.) (3.27 g (0.03 mole)) that served as an end-capping agent were dissolve in N-methyl-2-pyrrolidone (also referred to as “NMP”, hereinafter) (80 g). 3,3′,4,4′-Diphenyl ether tetracarboxylic dianhydride (31.2 g (Manac Incorporated, 0.1 mole, ODPA)) was added together with NMP (20 g) to the solution, and the resultant solution was reacted at 20° C. for 1 hour and was reacted at 50° C. for 4 hours. Subsequently, xylene (15 g) was added to the reaction solution, and the resultant mixture was stirred at 150° C. for 5 hours while azeotropically distilling water together with xylene. After the completion of the stirring, the solution was introduced into water (3 l) to produce white precipitates. The precipitates were collected by filtration, then washed with wate...

-Soluble Resin (A-2)
[0295]Under a dried nitrogen stream, ODPA (31.0 g (0.10 mole)) was dissolved in NMP (500 g). The hydroxyl group-containing diamine compound (45.35 g (0.075 mole)) produced in Synthesis Example 1 and 1,3-bis(3-aminopropyl)tetramethyldisiloxane (1.24 g (0.005 mole)) were added together with NMP (50 g) to the solution, and the resultant mixture was reacted at 20° C. for 1 hour and was then further reacted at 50° C. for 2 hours. Subsequently, 4-aminophenol (4.36 g (0.04 mole)) that served as an end-capping agent was added together with NMP (5 g) to the reaction solution, and the resultant mixture was reacted at 50° C. for 2 hours. Subsequently, a solution prepared by diluting N,N-dimethylformamide dimethyl acetal (41.7 g (0.35 mole)) with NMP (50 g) was added dropwise to the reaction solution over 10 minutes. After the completion of the dropwise addition, the solution was stirred at 50° C. for 3 hours. After the completion of the stirring, the solution was cooled to ...
